Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is: to provide an assembling connecting piece for a hollow elevator guide rail that can make the assembly of the hollow elevator guide rail very simple and convenient.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: an assembling connecting piece for a hollow elevator guide rail, the connecting piece is a stamping part with a "U" - shaped cross - section, and the stamping part includes: an assembling positioning part arranged in an inverted "U" shape, and a pair of fixed installation edges respectively bent outward at the bottom ends on both sides of the assembling positioning part. A plurality of stamping holes are formed by upward stamping on the fixed installation edges, and threads are provided on the hole walls of the stamping holes to form installation threaded holes.

[0005] As a preferred solution, in the assembling connecting piece for a hollow elevator guide rail, the assembling positioning part has a positioning convex part protruding outward at its upper part.

[0006] As a preferred solution, in the assembling connecting piece for a hollow elevator guide rail, the protruding heights of the positioning convex parts on both sides of the assembling positioning part are equal.

[0007] As a preferred solution, in the assembling connecting piece for a hollow elevator guide rail, the distance from the vertex of the assembling positioning part to the bottom surface of the fixed installation edge is equivalent to the height of the inner cavity of the hollow elevator guide rail.

[0008] As a preferred solution, in the assembling connecting piece for a hollow elevator guide rail, the fixed installation edge has an installation convex part protruding outward, that is, toward the side opposite to the assembling positioning part.

[0009] As a preferred solution, in the assembling connecting piece for a hollow elevator guide rail, the protruding heights of the installation convex parts on a pair of fixed installation edges are equal.

[0010] As a preferred solution, in the assembling connecting piece for the hollow elevator guide rail described above, chamfers are respectively provided at the four corners of a pair of the fixed mounting edges to form guiding slopes.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. The assembling connecting piece of the present utility model is a stamping part with a "U" - shaped cross - section. On the one hand, it is formed by stamping and bending, which strengthens its strength. On the other hand, during the stamping process, a number of upward - protruding stamping holes are synchronously formed on the fixed mounting edges, and then tapping is performed on the stamping holes to form installation threaded holes. The stamping holes correspond to the installation through - holes opened on the hollow elevator guide rail. During installation, both ends of the assembling connecting piece are respectively inserted into two adjacent hollow elevator guide rails. After selecting bolts and sleeving washers, they are inserted through the installation through - holes of the hollow elevator guide rail and pre - screwed into the corresponding stamping holes on the assembling connecting piece. Then, after appropriate adjustment, the bolts are tightened.

[0013] 2. The present utility model is provided with an outward - protruding positioning protrusion part on the upper part of the assembling positioning part, so that the positioning protrusion parts on both sides of the assembling positioning part are closely adhered to the corresponding surfaces of the hollow elevator guide rail. In this way, when assembling the hollow elevator guide rail, there is no need for adjustment, and the screws can be directly tightened.

[0014] 3. The present utility model forms a symmetric structure by making the protrusions of the positioning protrusion part on both sides of the assembling positioning part have the same height, which greatly facilitates the installation of the assembling connecting piece.

[0015] 4. Since the distance from the vertex of the assembling positioning part to the bottom surface of the fixed mounting edge is equivalent to the height of the inner cavity of the hollow elevator guide rail, the present utility model can be very smoothly fixed in the hollow elevator guide rail.

[0016] 5. The present utility model is provided with an installation protrusion part on the fixed mounting edge of the assembling connecting block, which protrudes outward, that is, towards the side opposite to the assembling positioning part. This makes the assembling connecting piece tightly arranged in the hollow elevator guide rail, further eliminating the gap between the assembling connecting block and the hollow elevator guide rail, and enabling the assembling connecting piece to be more smoothly fixed in the hollow elevator guide rail.
